CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 305,607, dated September 23, 1884.

Application tiled February 7, 1884. (No model.)

Jb all whom it may concern:

Be it known that I, EDMUND T. LEONARD, of the city of Baltimore and State of Maryland, have invented certain Improvements in Car-Couplersl` of which the following is a specification.

This invention relates to certain improvements in that class of carcouplers in which the introduction of the link to the draw-head displaces or forces back a support for the coupling-pin, and allows that device to fall through the link and to its proper position.

In the accompanying drawings, forming a part hereof, Figure I is a longitudinal section of the coupler, with the'couplingpiu sustained in an elevated position. Fig. II is a similar view ot' the, coupler, with the coup- Fig. III is a sectional plan of the coupler. IV illustrates a modified construction of the coupler.

A is the draw-head; B, the coupling-pin,and G the link. D is the support for the pin B; and it consists of an angular arm the rear portion of which `rests in a cavity, a. Apro- 2 5 jection, b, on the front face ofthe upright portion of the-support D, serves to force the link outward when in an inclined position,as shown by the dotteddelineationof the link vin Fig. II, and also to sustain the `said link in a horizontal position when the adjoining coupler is on the same plane with the one shown in the drawings. The upper end, b, of the support D enters au extension, a', of the cavity a.

This extension is of such size as to prevent y the overhanging portion of the support D from passing too far beyond the edge of the coupling-piu and without the assistance of any exterior devices. The material against which the rear side of the support D comes in contact is 'sli ghtlyinclined from a vertical lineor, in other words, overhangs, in order that the said support cannot be brought to an absolutely vertical position, and consequently a forward movement is initiated without depending on the overhanging portion of the support to effect that result. The lower end of the said support is pivoted at c.

By referring to Fig. III it will be seen that the cavity a is deeper than the Width of the support D. Consequently the said support when forced back in the coupling operation is not liable to injury, the shock being sustained by the draw-head, and that the edges d are slightly rounded to prevent their being broken.

In some cases I apply a shell having an inner contour corresponding with that shown in Figs. I, II, and III, and provided .with the improved support D, to an ordinary coupler, as shown in Fig. IV.

In a car-coupler, the draw-head A, having the pin B and the cavity a,with its extension, a', combined with ythe support D, the upper end, b', of which enters the said extension a', substantially as and for the purpose specified.
